Participant observation is a research method used in social sciences where the researcher becomes a member of the group being studied and actively participates in their activities. However, there are numerous synonyms for this term, including fieldwork, immersive research, experiential analysis, contextual inquiry, and ethnography. Each of these terms signifies a similar research approach where the researcher immerses themselves in the culture or community they are studying to gain a deeper understanding of their behaviors, values, and way of life. This approach is common in sociology, anthropology, and psychology and allows researchers to understand the subject under investigation from an internal perspective rather than an external one.
